I am looking for a single noun similar in meaning to weekly contributor, but possibly of Latin or French root. (I am thinking that there has to be some version of French semaine used in English.)
The goal is to have a name for a participation badge on my website (think of Stack Overflow badge system). The badge would be awarded to those who participate in a weekly contest (for a number of weeks, without missing a week).
So, I am looking for a noun that describes somebody who does a weekly action. Ideally the noun would be derived from a verb to imply action. Something like "Weekly contributor" (or just "Weekly"), but in a single word and with a dash of grandeur and loftiness if possible.
Edit: I would accept a word that just hints at "weekly". The contributor part would be nice but isn't a must.
