would it sound weird to ask for a professor to be as a permanent reviewer of a journal or conference?
It doesn't seem odd at all. You can simply ask a &quot;good&quot; reviewer if they are willing to review again in the future. I suspect many will say yes and some will fail to respond.
When you ask, you can also ask for subjects/topics that most interest them. This would ease the work of the program committee in the future, as they would be a bit less likely to send requests that are unlikely to be fulfilled.
Another approach, used by some CS folks is to put up a page with received papers, perhaps just titles, and send out a broad appeal to previous reviewers (and others, perhaps) asking if they are interested in any of the papers.
