Just make sure you fill in all the requested information, all of which can be found quite easily by anyone. I already sent a request to have the wallet updated but it can't hurt if more people send one, and may get the wallet back up and working faster.
The disappointing part of this is that other coins have sent in BTC for priority service and still waiting weeks or even months for the wallet to be back online. So I won't be spending BTC for priority. However, I DO tip the support when they do fix things!
I am still deep in other projects, but the XMINE project will continue development during the coming months. It just a matter of how much I can free up my time.
The website could use some help if anyone is interested in contributing some time to this. The website is there, just need people to contribute some content and graphics if your interested.
