I think I know the answer to this, but I want to double-check with you nice people to make sure I'm not going to do something foolish when I'm trying to do something Foolish.

This year I changed jobs and rolled my 401(k) to a Rollover IRA which I have subsequently converted to a Roth Conversion IRA (held by Fidelity).

Now, before the tax year is over, I want to make an additional contribution to my Roth. So my questions are:

1) Am I allowed to make the contribution having done a conversion this year?

2) If so, are there any limits on the amount I can contribute (except the obvious 2,000 annual limit for Roths)? I contributed to my 401(k) from January to May of this year.

I believe that for my situation, I'm allowed to make the full 2,000 Roth contribution this year and I can put it in the same Roth that I converted. Is there any reason I wouldn't want to do this?

Thanks in advance,
