I think that would be interesting to have categories defined to find easily some post. Some categories that could be created:
News/Announces (probably limited to new versions of CCX)
Compilation (there are a lot of posts about these subject)
Feature requests (I think that this will be empty, I don´t see too many requests)
Bug Reports
General Questions (maybe two, one for CCX and other for CGX)
Benchmarks/Comparatives (they are very usefull to gain confidence and know the limitations. Very often our clients ask for some validation cases and this place could be a recopilation)
Gallery (a place where we can gloat over our best simulations 
)
