It's not really an answer, but my thoughts are too long for a comment.
First of all, I'd like to thank you for all the effort you've put into
moderncv and the time spent in helping people here.
I really share your worries on some MWE lacking the minimal component. Indeed we have quite a bunch of such examples in our community.
I once stumbled upon one of your edits and, although your changes in the code really reduced it to the minimal example, they were quite significant. I decided to abstain from voting for that particular revision - and then someone else voted.
I'm very happy to see improved questions and answers. We have great TeXnicians around - Heiko, Frank, egreg, David, to name a few - but we also have a lot of TeX newbies. IMHO writing a MWE is also part of the learning process. We have successful stories in which problems were solved by simply trying to come up with a MWE.
I think a good approach would be to ask the OP, via comment, to try reducing the code to a minimal state. I see this as a win-win situation:
- The OP can learn from the process and maybe even solve the original problem.
- The community will have a concise code and a better question.
I'm also tempted to reduce codes to their minimal form, but I can see the benefits of leaving the questions as they are for a while. As TeX shepherds, we are happier about that one sheep that had a good learning experience than about the ninety-nine that did not need guidance.
