Domain names question. Urgent!

[aaandy]

Hey guys!

I need some help in picking up right domain name. Currently I'm developing new script and I have some other projects in mind so I'd like all the domain names to be in same format.

Which format do you prefer?

1script-2u.com
2script-2u.com
3script-2u.com
etc...

or

1script2u.com
2script2u.com
3script2u.com
etc...

where 1,2... script are the names of the script. It is single keyword.
Keep in mind that I'd like those domain names to be easily branded and promoted in SE.
Any thoughts on this?

Thanks,
Andy

Without dashes.

Certainly without dashes and memorable one.

The idea of the hyphen is to seperate out keywords (in the anchor text) for anyone linking to you using the your URL.

Using 2u which isn't a popular keyword (as far as i know) there's no need to seperate it but if your 1, 2 or 3 with 'script' are popular phrases you may want to consider using a hyphen, eg. java-script2u.com or php-script2u.com
