I cannot commit to a daily check. Some weeks, I spend many hours on LT, some weeks none. In principle, I'm happy to review the suggestions from users. But, I will then have less time to fix the other suggestions/corrections that users send.
A page on which users can supply suggestions is a good idea.I don't know how the system works for German. This is what I would like to see for English:
For each suggestion, a user should supply a minimum of one example sentence and a reputable source (Webster's, Longman, Shorter Oxford, ...). Ideally, on the page, have a status indicator for each term (submitted, accepted, rejected). For the rejected, give a reason. (This is similar to the method used for dealing with comments during the development of an ISO standard. It shows that we take comments seriously.)
Sort the suggestions alphabetically.
Do not let a user suggest a word that previously was suggested. Just give a message 'previously suggested' and link to the existing suggestion (which will show its status).
