Looks like your campaign is back on schedule for payments and the system is online again (no message on the main page anymore stating it is in maintenance like another campaign has with aug26th to wait   ).
So my question is when you are going to be out of beta mode and start allowing more members to join in to this campaign. I would imagine a lot of members have been patiently waiting to be able to join in to this one including myself.
The system's bugs seem to be ironed out as you put it and people are starting to a bit more faith in what you are saying and have a sense of guarantee in this campaign running professionally from now on. And having a maximum payment button is not a top priority right now as I think most participants of your campaign would agree with. They would just like to be credited as they should and receive payments instantly (well fairly) when they request it from the system instead of on a weekly basis. I think that would be a feature most if not all participants would like to see enabled instead.

Cheers and continued success to you Namworld!
