Is the theme coding ok

[Newjabber]

Hi

I have alot of WP sites and i dont know if the code of the different themes im using is ok. If there is something i have missed to optimize my site etc.

I looking for someone to have a quick look at the coding of my sites so i an find out if i should replace the current themes or if there is something else im missing.

So, if its something you could help me with it would be great.

I can offer some blog posts in return for the help.
