I like your plugin but I have a lot question, may you help me:
1.-Does the buyer need to have an account (in my website) with his PayPal Email Account? What happened if they use different account emails?
2.-Can I add a commission with percents (like 20% of the total amount transfer)?
3.-In the demo, you deposit $50… who receive that $50? the admin? where is the money, PayPal?
4.-What happened if an user deposit $50 but he doesnt buy anything and need a refund the $50?
5.-In minute 4 of second demo video… It looks like the seller can withdraw part of the money right? It means, as admin I keep the rest in my PayPal account?
6.-Suggestion: You should change the status info from 0 and 1 to pending and paid… in withdrawal request page.
7.-I think the option of withdraw is enough for the system… It will be really easy, just accept or cancel de transaction as admin between seller and buyer. With your system, Admin needs to be more worry about transactions, etc. Just is my point of view…
8.-To use your plugin do I need an approved APPID on www.x.com? whats is that?
9.-How I can add more payment gateway?
10.-Does PayPal charge me a commission or fee for each deposit and withdraw request?
11.-You say the plugin is compatible with Buddypress? how are they compatible?
I am sorry, but I want understand your plugin.
