I've never noticed before that there isn't an on/off switch for Member's Signatures. (I've always thought there was).
There was a C_STRSIGNATURES field in FORUM_CONFIG, but it wasn't declared as an Application Variable in config.asp. The conversion to FORUM_CONFIG_NEW wiped the C_STRSIGNATURES field.
Plus, in inc_profile.asp there isn't an if/then statement to see if it's enabled.
actually, the strSIgnatures variable is in the new setup, as I posted a bug about it a couple of days ago, saying to remove it as it wasn't used in any of the code files.
I think all Gor did was to put the application Variable back into config.asp. The code in admin_config_features.asp, inc_profile.asp, post.asp & post_info.asp still isn't there. We'll get that fixed before the next release.
