Well maybe it's just me, but I would really like to have the possibility to ask for proofreading from other members.
For now, as far as I see it, the ranking system is often confused with the "thanks" mechanism, and despite the good idea of adding some comments along with a rating, I see it used mostly to give 5 stars as a "reward" to the translator regardless of the percieved quality of the translation.
Besides, I kind of dislike this confusion between assessing the quality of a translation and giving advices. Putting low marks to the translation of a difficult text may be consistent with the rating scale, but will not necessarily take into account the work that went into it.
In order to avoid these kinds of ill effects, I think it would be great to have a simple system for marking a translation for proofreading, so that people interrested in that kind of work could see easily where their help is wanted.
The translation author could then decide to end/cancel the proofreading request once he/she is satisfied with the results.
I don't think any other special mechanism would be needed : wanabee proofreaders could use the existing interface to add comments or send PMs to the translator.
I as I imagine it, it would require the following new items:
- a "request/cancel proofreading" command for the translator (be it located on the translation page itself or on the user's profile translations list)
- the possibility to search the database for proofreading requests (similar to the translation requests search)
- possibly a new section on the right side (similar to "help to translate")
- possibly a new list of proofreading requests on the profile page (so that a proofreader could, for instance, see for which songs a given member has requested help).
In order to avoid cluttering the database with a lot of "dead" proofreading requests, they could be reset automatically after some time (a few months maybe).
What do you think?
