Some thoughts.
If this site is aimed at non-techies they will panic - the language will seem geeky to them, and put them off because of their perceived lack of ability - just the phrase "free matching algorithm" will have them quaking in their boots. - try and make it a bit less jargony if you're interested in attracting that audience.
Tech point - The javascript fell over on this page:
http://www.matchimedia.com/search/Pe...d-Relationship and all my nav broke. Also from an accessibility point of view, using scripting like this is an accessibility issue - plus when the script breaks, so does your nav. I would consider a different implementation here for those reasons.
I searched for "jobs" with the "UK" radio button selected. None came up. It just said search results.
It leaves a user thinking:
- was the search broken - It didn't even say 0 results?
- did I type in the wrong term? If so, what's the right term, careers? Employment? There were no tips or synonym matches.... to help me
Or where there simply no matches?

It said there were 17 matches for "job matching", so I am not sure why there was nothing.
That could do with tightening up - it's going to cause confusion.
Also I ws getting a javascript error

I saw the members online section. I wasn't sure what that did - until I realised you have to register to appear - that might put people off, they might want to do private, unmonitored searches and not realised that unregistered means the searches are private.
On the search people page, it's asking stuff like sexual orientation. I think if you're going to do romantic/adult matching you should keep that separate from stuff like jobs - I think that confuses the site purpose, and some people are going to be put off by adult stuff appearing (for example they use the site at work for other purposes).
Hope this helps.
