Word order in imperative sentence

What are the correct possibilities for word order in the following sentence?
Is there any general rule for imperative sentences? (Like SVOMPT?)

1. Please, check regularly the updated information about the meetings on the EBC website.


2. Please, regularly check the updated information about the meetings on the EBC website.


3. Please, check the updated information about the meetings on the EBC website regularly.

Something is telling me 1 isn't entirely correct, 2 maybe. I think 3 is correct, however I don't like the word regularly to be so far from the words check and information.

EDIT: attempt to summarize the answers:

• #1 sounds awkward to most people except for Barrie


• #2 seems to have least opponents


• the comma should be omitted


• new solution raised (from Hellion & Barrie England):

4) Please check regularly for updated information about the meetings on the EBC website.

Do you all think #4 is the best?
