Just to clarify... what topics subjects are you referring to? ( See attachment for clarification)
The title of the posts of the homepage (see marked 1) or the ones in the Recent Post block (marked 2)?
The display under 1 is no under control by TinyPortal, that is theme based... if it is the second you mean, need to check...
In addition: you are 4 versions behind the latest TP version... suggest to upgrade to 1.6.3...
One more thing: you seem to have removed the TP copyright from your site, which basically indicates you are not interested in our support... please be so kind to put it it back...
