Since some time I'm using [Subtitle edit](http://www.nikse.dk/subtitleedit/). The author, Nikolaj Lynge Olsson, has a very decent help file on his site. Despite that, people of course still have questions (I just mailed him one).<br />
You can email him, he'll answer sooner or later (I don't know how fast, usually), and I have also seen the occasional answer from him on miscellaneous forums.

*I'm thinking of suggesting him to take his support to SU*.<br />
That way he would only have to check one site for questions, other people can contribute as well, and the answers benefit more people at once.

- Is this OK here? (I don't see anything in help or meta against it, and there are many program-specific tags already)<br />
- Are there any special requirements?

And we would need a tag, of course (<kbd>subtitle-edit</kbd>?)
