Is this adsense in a phpBB forum ok?
 

www.digimonforum.com

I made a little change in a tpl file so that I placed the adsense right above the forum but then I found out it could be done like this instead. Just having the adsense script in the topic description but no topic title.

Since it is so close the forum topics, maybe this way isn´t allowed?

Yes you can add google ads on phpbb .. check out http://www.dadesideals.com

I went to templates and chose the overall_head.tpl file and make the changes... let me know if you need help.
