Sometimes, for example during the night, I edit some post, and I get 2 reputation points. The day after, though, the +2 has disappeared. I check to see if I had a downvote or something, but the log shows nothing. Recently, it happened more than eight times to me. Is it because I should be the last editor of that post to get the score. Am I right?
Some suggestions for you about editing:
- first, make sure you get everything in a post. Typos and spelling mistakes are great, but there are other things you can clear up in the suggested edits of yours that I checked. Meta talk like "I don't know a lot about this" or "Thanks so much to anyone who helps me" should generally be removed while you're there.
- second, do not try to make answers correct (your objections to the edits on this meta question suggest to me that you think edits are for correctness.) Edits, especially suggested edits that have to be reviewed, are for style issues like spelling, grammar, word order, expanding abbreviations and numerals, capitalization, and so on.
- third, if a question is very bad think twice before investing your time in it. If it is deleted, whether by the asker or the community, you will lose the rep you gained.
- fourth, remember that users with over 2000 rep are considered to have learned the editing rules: their edits are not reviewed and they do not get rep for editing. If you don't like an edit, you can roll it back.
And finally, if you're going to participate in meta, you will have to take the good with the bad. Meta often doesn't agree with people who come here to say something isn't fair.
