Another suggestion. I most often ask for compounds that are described seomwhere, either on a web page, in a IUBMB EC entry or in an article.
It would be nice if you could provide evidence links, e.g. URLs, pmids or EC numbers to descriptions of the molecule. In my current suggestion I have placed this evidence in the definition field. Perhaps also a "Additional comments" or "Additional evidence" field allowing free text would be helpful? Ah, ah I just found the possibilities to add comments.
The comment filed should be more prominent, for example in submission step 1 placed under the charge with a pre-created text box ready for use.
It was a mere coincidence that I saw the other possibility (5th time looking).
