It would proabably be better if TP supplied containers for meta/OG tags itself, adding it to the the headers dynamically, than letting a SMF based mod do it. But that may not be something planned in the near future so I guess its a moot point.
Hi bloc, great to see you posting, long time no hear.
meta/OG tags stuff incorporated into TP has been mentioned recently, but not sure any of us understand it enough, or have the time atm to do anything with it.
Personally I don't have any php articles, or not ones I'd want to share, they just get used to run scripts more than anything. I should imagine the majority of articles will be written in either bbc, or html. The Optimus mod does seem to cope with those pretty well, just have to give some thought where you place stuff.
