Feel free to use whatever part of it you want Alana. I haven't actually completed a swap myself and am totally new to the site, so I have just been reading about the new system in various threads trying to figure it all it. I wasn't able to find a single guide to the new system that brings all the information from the forum postings together...perhaps because it is so new. I think I learned about the plant list uses from watching a You-tube video on the All Things Plants channel.
One thing I think this site could use is a FAQ section someplace really obvious and not just posts in forums. It would help new and existing users use the site to its full potential. Some things are intuitive, but others not so much. I was especially confused by profile settings. When you say you want to watch or follow threads, I was thinking that meant get an e-mail, because that is how most other forum sites I've used do it. So that is going to take a bit of getting used to. Overall though I am very happy and I think this is the most flexible and feature rich gardening site I have tried so far. I've been trying out the multi-plant image tagging which is pretty neat. I've finally found a good use for all the plant pictures I've been taking over the past decade. I'd rather have them added to the plant database where they could be of use to others than just sitting on my computer "collecting dust."
