Various questions (issues) seem to exist about users who forget to mark "an" answer as the accepted answer. Maybe adding a friendly reminder near the end of an answer would help to address this issue. Eg with something like so:
PS: If this answers your question, then please mark it like so (using the checkmark below the vote up/vote down icons next to this answer). Doing so you will comply with what this site expects you to do, and you will reward the user that actually answered your question (something many users seem to forget, which is why I mention it here).
- is adding such reminder "appropriate", i.e. that it does not violate any rules I'm not aware of yet?
- If it is appropriate, what would be a good template to be used, to enhance my first draft version of what I suggested above?
- Also, if these about 4 lines would be perceived as too long, how about just adding a link to some kind of template for it, With a title like "if this answers your question, then please do not forget to mark it as such".
