What would you like done?
A way for users to add their minecraft account or username to their profile and have it either send a rcon command to the server whitelisting them or some sort of plugin integration with waterfall/spigot/bukkit
When do you need it done?
No rush. Just don’t see it as a current plugin for this platform where there are multiple available for things like xenforo, vbulletin, phpbudy, etc.
What is your budget, in $ USD that you can offer for this task?
I’m a small community and this plugin isn’t integral to our workflow. I could cobble together a small amount towards your efforts. I don’t know how difficult what I’m requesting to be done is, so I don’t want to presume it’s value/cost.
