Daniel. The Forum is very welcome, but you have some serious competition and are at present "chasing the game".
1.There's far too much reliance on "latest posts" rather than a more differentiated approach. Gardenweb has over a hundred different forums. Now that's too many but there has to be a happy medium.
2. Also, I've noticed a lot of people don't really know how to use the site to best advantage. Like a good gardener you need a little patience. The first answer you get is not always necessarily the best and yet a lot of people don't come back.. It's not a chatline. Many people may only visit the forum occasionally and yet they have valuable advice. Besides I'm not going to comment if 20 people already have. Even if I think 19 of them are idiots!
3. The photo reproduction is insufficient. Far too small to be useful. When I tried to redirect to a photo hosting site, I was unable to do so.
Good luck and hope you find this constructive.
