Link Multiple S2member sites and accounts

i have a question about connecting the accounts of two separate wordpress installs each running s2member. I’m using s2member on the first website with 3 levels lets call (free, silver, allstar) and the second site with (free, premium, allstar). The all star packages need to be linked so the user has access to both websites whilst the other levels are not linked.

is there a way to automate this joining process such that an account created on the second site will also make one on the first (would be great if they were the same username but not imperative if another way would have to be used)

any ideas?

let me know if that is enough information to go by. thanks for your help in advance

i’ll admit my own ignorance with this plugin so perhaps this is not possible or so easy its laughable…

but what i’m thinking is if i use Paypal to process payments for the level 4 from the First Site, is there an advanced variable or IPN info that will send the account registration to the level 4 of Second Site’s S2member plugin?

so that the user has access to both?

or perhaps there is another way to grant access to both sites…. any ideas? thanks in advance
