The same problem does not exist in RM, in Construct companion we have Golem creation on page 45 and Amalgam creation on page 89.

You didn't check Construct Companion very carefully.

Describing Amalgams on p. 14:

These Amalgams are sometimes erroneously called Flesh Golems.

Describing Golems on p. 13:

"Flesh Golems" are not in fact Golems as they are not composed of a single piece of material. Instead "flesh golems" are Amalgams

Construct Companion agrees with me that flesh golems were miscategorized.

Since that printing, ICE released the Oriental Companion and Arms Companion which introduced Martial Arts "stuff" geared for the RM system.  The points you refer to are from a time RM was like an "every man's system."  There are charts for converting D100 to other dice systems, references to Space Master and MERPS.  When I first started playing RM the GM was using some of the MERPS books because he liked the content better than some of the RM content.  Other GMs worked solely with RM and solely with MERPS when playing either.   Even in later Companions, there are crit tables included for use with Space Master (Shrapnel and Explosion, I believe are two that have footnotes stating as much.)

1) We did allow attacks to multiple targets in the same manner any other PC in the game could, with the same modifiers and restrictions.  We did allow weapon kata, but only if the player calculated all the stats for the attacks so the GM wouldn't be slowed down trying to do additional math.  As a result, hardly anyone ever bothered with weapon kata.

2) We allowed multiple attacks, again the same way any other PC could do them; Adrenal Speed, speed spell (or slow spell), magic item.

3) This is the same as item 1.

If possible, take a look at either of the Companions I mentioned, that may make MA a little more balanced for your game.  We've never run into an issue with Martial Artists being over or under powered in our games.  The smart players developed MA Strike and MA Sweeps and Throws for their PC.  It's more costly, but Sweeps and Throws on an armoured opponent produces crits at lower thresholds and Strikes does the same for lesser armoured foes... and it's the crits that kill in RM.

I don't agree that D&D defines what an Flesh golems means. Flesh golems as an animated pile of body parts stitched together and moving only due to golem magic is a common fantasy trope that exists in everything from live action movies to books. I have never encountered any Flesh golem while playing D&D, but have encountered Flesh golems in everything from RM to animes.

The weird thing about D&D is in fact that they insist on putting the Flesh golem classification on Frakenstein monsters despite the obvious differences to a golem. I suspect the background is that D&D recieved criticism about lacking rules for creating Frankenstain's monsters and the designer solved the issue by claiming their golem rules covered the Frankenstain case.

The same problem does not exist in RM, in Construct companion we have Golem creation on page 45 and Amalgam creation on page 89. Making it so that RMU cannot recreate the Flesh golem from previous editions because D&D have used the same monster name for other names is stupid. Considering that Nicholas wrote Construct Companion I think it is a given that RMU should stay compatible with previous editions so it is possible to make an updated Construct Companion for RMU.

Everything being viewed right now when I checked were a couple dozen forums opened only 3 to 6 seconds apart.
I'd bet a whole lot of money those are bots.

I've never seen consistent forum traffic like this, besides big releases or other notable events. I'm seeing 200-300 users/day. Is this bots or is there an increase in new user/unregistered activity? If it's new users how do we engage them more effectively? If it's something else, what is it?
