I can, since it's not forbidden by the forum rules.

Yes it is. It explicitly is.

Posting non-SRD Copy written content
Just mentioning a PrC or general mechanic that isn’t in the SRD isn’t a problem, but posting an entire stat block for a monster or class that has not been released under Open Game Content (OGC) is not allowed. It will be removed. Remember that, so far, only d20 products are published under the OGC.

EDIT: Changing this a bit so it isn't quite so harsh. Basically, by my interpretation of that rule, you should only post very vague descriptions of things, while posting mechanics (even fluff mechanics) that aren't in the SRD goes against that rule.
