English is a foreign language to me, and I solve the problem using Vim for PerlMonks nodes and VimSpell, both integrated with some human judgment.

YMMV, but you may use a similar off-line solution (as belg4mit suggested) to deal with misspelled words before posting.

I don't like the idea of an automatic spell checker.

Checking a PM post is not a task that can be idly assigned to a spell checker. You want to spell-check your statements, but spare everything inside a <code> block. OTOH, comments and POD inside a <code> block should be checked as well. Not your ideal candidate task for a spell checker.

What then? I suggest using an off-line checker and applying some human knowledge of grammar: such combination is better than any automatic tool I have ever tried.
