OpenEMM Support

hi everyone

i'm new to OpenEMM

question about loading recipients in bulk.

i'm running on a VPS, i've editted the load limits, and so far,
the practical limit seems to be around 30k of addresses / CSV.

has anyone worked with loading thru the backend?
meaning, directly loading into mysql, probably using myphpadmin.

is there any kind of stored procedure to load thru? to ensure proper
recipient creation? with all of it's details.

thx
cheers
