A few projects have requested it, now it is here! Check out https://translate.apache.org and get your project added.
See also https://cwiki.apache.org/confluence/display/INFRA/translate+pootle+service+auth+levels for more information - you will see that general public non-logged in users can submit translate requests whilst any logged in user (i.e. - committers) can process those submissions.
Enjoy! - Any queries to the infra team please or file a INFRA Jira ticket.
