Some Personal DataEdit

I live in Uruguay and I'm a teacher at the state university (Universidad de la República) in the Computer Institute of Ingeneering School (Instituto de Computación, Facultad de Ingeniería).

Why I use MediaWikiEdit

I'm trying to use MediaWiki as communication way for several projects. As an effective replacement to BSCW.

Extension in UseEdit

I'm using extension:PageSecurity and User:Hex2bit/Calendar. Also I have a "dirty" extensions to protect SpecialPages based on groups.

I need...Edit

  • Lean php, a lot more.
  • An english course! (yes, I know !!!! sorry :-) )
  • A lot of other things...

ContributionsEdit

  • A modified version of PageSecurity which allows a user if he belongs to an allowed group... or not... If the variable $wgPageSecurityAllowGroupAccept is false or not set, then is the normal PageSecurity. If the variable is true then a user is allow if belongs to an allowed group. The modified code is here.
  • An extension that can control the access to SpecialPages based on groups. The code is here.
