Adam, I have just had a look at the Photography Friends site and I believe you could have something worthwhile there but at the moment it does look rather uninviting because of the lack of members, photos and colour scheme. I am the kind of person who doesn't usually sign up to anything unless it already has a good following and looks visually appealing (although this isn't as important; it is the quality of the material contained within it that's comes first). However, saying that, presentation is key and it is the look of the site that ultimately decides whether or not anyone is going to stay on there long enough to be curious and look around. You have to sell the site to people visually, if that makes any sense.
Firstly, what I have to say is not to be taken as an attack on your efforts, because it isn't; I know what it's like to set up websites and the hard graft involved in making them visually appealing and user friendly. I must say though I am not a web developer or programmer, just a guy who has learned the hard way myself and had a lot of help from a colleague who knows more about websites than I.
1. When the site fills out a bit more it will look a great deal more interesting but the rather low-fi look and feel of the site still makes me want to close the page immediately simply because it doesn't grab my attention at all.
2. The blue and grey colours and the bold menu fonts do not scream
'welcome to this site, have a look round and join our community'. Colours are very important as are the font types and I am thinking maybe a better looking theme would go a long way.
3. The white background is fine and looks clean. The other option is to incorporate black. You need to choose something that really shows off and compliments people's photos and both black or white are good candidates. (I see you have black in your djsupport site)
4. It's always a good idea to ensure that all your links lead to pages with information and not
This page has not been set up yet. People will switch off straight away if they can't read up on the Terms, Disclaimers, Privacy Policy. A lot of people want to make sure they are not sighing up to something that will harm them in some way, regardless of whether it is free or not. People are cautious and quite rightly so. Put your site into maintenance mode and fill out all the pages before making it live again.
5. If you can, move the login box. It's too much in your face. The top of the page is what grabs people so put some welcome text here (only short) with recent uploads or a slideshow, photo of the day etc. or anything that get people's attention straight away. Eye catching is key.
6. Don't just limit your demographic to the UK.
7. Delete some of the test stuff you have added and upload a a lot more of your own work.
I run a wiki, a forum and now recently a photography site, which I set up as a bit of fun to show friends and family some of my photos. I too work full time and know how difficult it is to juggle work and home and there are times when I feel like I monopolise the computer.
I think the site could be great but it does need some attention. I will be happy to offer other suggestions if you have any questions and I'll sign up for a test account. The above is just a quick run down on what stood out to me. Hope this helps.
