Just some thoughts to keep in mind from my personal opinions...
The Guild Companion, Guild Companion Publications and Aurigas Aldebaron LLC are all separate legal entities.
AA allows GCP to use the IronCrown web pages because GCP has a license to produce AA owned IP products.
TGC is separate, and intentionally so. TGC does at times share materials that are not ICE related.
A few comments about blogs... Some bloggers do a great job. They put in the time and energy to continue to add content, and make a solid effort to provide quality material every time. That is truly rare though as most individuals start with grand aspirations, and then fizzle out after a few posts.
Blogging on ICE website... Bad idea. It immediately draws into question the objectivity of the blogger, and adds extra work for ICE personnel to have to monitor and manage. We already get enough undesired spam hitting the forums. Trying to monitor blogs and the comments to them would be a real pain.
Blogging at TGC... Sounds like a good idea, though there is something to be said for the quality editing work that the folks at TGC do - and the monthly aspect gives you a little more volume rather than going to the site for each individual article. I guess as long as they use the push out notification process, they could move away from monthly and simply go to as ready - but that's a TGC discussion and I'll leave it to them to figure out what works best.
Blogging on the internet... Best solution. If there are people that want to blog, do it. Tell us about your blog and provided you don't spend your time trashing ICE, we'll probably help you out in promoting it - including links from Facebook, forums, or potentially even our newsletter.
As for the comment about formatting and losing stuff on the forums... The search function works pretty well, and with attachments you can do just about any kind of formatting you want, but I do understand it's not the same as working on many other programs.
