"Signing up for newsletter" messages

My "Current newsletter subscriptions" are:
Job offers
New Drupal events anouncements

And after registration I've receive double messages:

* Signing up for newsletter.
* Signing up for newsletter.

Is it issue?

Would it be better to use:
Signing up for newsletter "Job offers"
Signing up for newsletter "New Drupal events anouncements"

Or:

Signing up for newsletters:
- "Job offers"
- "New Drupal events anouncements"

And one more:

@anouncements@ should be "announcements" with double "n"

Можливо це все не так і важливо (Так на разі побудований Друпал), але бачу нічого люди тут не пишуть, то вирішив якось всіх розворушити :)
