Generally if you want help with an addon you should:
(1) Provide a link to the addon's download page. People are more likely to help you if they don't have to go hunting on Google to figure out what you are asking for help with.
(2) Describe specifically what is wrong with the addon, not just "it doesn't work" or "it needs an update". Again, people are more likely to help you if they don't have to install the addon, load it in-game, and play around trying to figure out what's broken.
If the help you're looking for is "someone update this abandoned addon" it might also be a good idea to describe the specific features you need, since there might already be another addon that's not abandoned that provides the same features.
It's on Curse. Why would I have to post a link to it when it's on Curse? But okay.... there's even a problem doing that. About a year ago it was "forgotten" to add it to the total Xbar package. This was probably due to it not having to be changed in any way for many years. But suddenly it was missing from the package.
I will get it added back in when it's fixed. The OTHER problem is that, when the addon's author, DrDoom got a job in his field, he left in a hurry and made the first person who expressed interest in taking it over in charge of it. And judging by our communications I would place that person (ncplus) at approximately 10 years old!! This child is the age of my grandson and doesn't have a clue how to fix it, nor do I. He is asking for help with it. I have no lua experience, but I'm willing to try.
