I asked 2 questions which in hindsight probbaly should be community wikis
However, when I select edit, I dont get the option to convert to community wiki. Any idea why?
Dealing with women (or opposite gender?) when they quote "Medical issues"
How do you avoid interviewing for the company you work for?
Should they be CW? if so, how do I go and make the change? (I seem to remember being able to do it a while ago on another SE site, but I might be wrong)
I'm not sure if this is the reason you can't, but note that both of those questions have answers. Community Wiki on a question affects all answers too (from that point forward), so it makes sense to me that the asker of a question shouldn't be able to force that change on answerers unilaterally. Making this change shifts the functional "ownership" of a post away from its author and also denies further reputation changes, which really only makes sense if a bunch of people are going to be sharing in the writing/editing of a post.
Community wiki is best used from the start, to allow the community to assemble a single canonical answer to a question. Its benefit is less clear to me when a question already has a bunch of answers. Community wiki is pretty rare, and Stack Exchange has been discouraging it for the last few years.
That said, moderators can convert a question (and thus its answers) to community wiki. We would want to see clear consensus from the community on any specific proposal first. For these two, I suggest you add one answer for each explaining why that question should be CW, so the community can vote on your proposal. For future cases, just ask a new question, like people do when proposing that something be closed or reopened.
