On the Terms page, you refer to SkillSearch, which confused me - isn't it SkillSwap?
Typos: on the 'About' page - first paragraph, 'loosing' should be 'losing'
Also on the Forums main page, Fermannagh should be Fermanagh
I missed the forums first time around - it's not in the footer menu or your tabs menu. Conversely, About isn't in your navigation menu.
Also, on the navigation menu, I get a green tick beside the current page for 'Contact' or 'Forums', but not for 'Home'.
Probably just me, but I didn't initially realised that 'Create content' is effectively a sub option under 'Forum' - I thought it was another section in it's own right. Might be clearer indented?
Finally, your introduction ends with "use the contact form on the left to contact us" - there is no form on the left, maybe change to "use the contact form to contact us" and just link to it?
Like the idea , good luck with it.
