This question got migrated from the main site.
The user has been asked for clarification in comments, but that user has only 1 rep. Can such a user answer, or update her/his post, if (s)he hasn't got the minimum of 5 rep necessary to participate in meta? Or can you always edit your own posts, even on meta with too little rep?¹
As that user has not other questions, it is impossible to "upgrade" the user by up-voting such a question (up-voting on meta has no effect on rep).
If I had realised this before, and up-voted the question before voting to move, would the rep have been lost by the move to meta?²
In principle this could also happen if a user a very few questions and answers and low rep, then posts on meta and her/his rep decreases by a down-vote or a changed/retracted vote. But then at least one can bump the less-than-5-rep, by up-voting one of the questions/answers on main.
¹ A move to another site would not be the problem, that should work as there is no minimum rep to participate, you just have to add that site to your account.
² Probably it is, I am just curious in case up-voting before voting to move, would help for a future occurrence
