To be completely honest, I hate textmacros. They're ugly, and make code confusing. The only reason I would write my own textmacro (which I have only done a few times) is to save a large amount of time and redundant code.
I supposed I would like them more if Vexorian would actually give them decent looking syntax, but he hasn't. I do like modules, as they look nice, and work well. Textmacros on the other hand just seem like a non-feature with huge potential for abuse.
General 'pick a random feature and talk' isn't what 'Discussion' tags were made for.
They were introduced so that once there were enough tagged threads, they would be moved to a separate Discussion sub-forum, and the tags would be removed.
Things such as bug discoveries, benchmarks and tips are included there (heck, everything that isn't a help thread, really).
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
