Tatoeba update (June 22, 2014)

• The fields for adding a new sentence are now easier to read and to type into, and clicking outside the field is ignored.

• Cleaned up the handling of tags as follows:
• leading and trailing spaces are now automatically trimmed
• tag names that are too long are now safely truncated
• tags whose names begin with "@" are not automatically deleted when the number of associated sentences drops to zero

• Cleaned up names of existing tags as follows:
• names of utility tags, which indicate sentences that need attention, now all start with "@" ("@check", "@delete", etc.)
• no other tag names begin with "@"
• rewrote tag names beginning with "By" so that they all start with "by"
• removed extra internal spaces
• fixed some misspelled tags
• consolidated some other tags that had multiple variants

• Updated the wiki page on tags.

• Added link to donation page to top menu.
