I've tried reaching out to you on steemit.chat few weeks ago as the steeminvite service hasn't been functioning properly.
Since then i've written my own JS script for creating new users via delegation, but also made this possible via my "GK Steemit Info" wordpress plugin.
Still, steeminvite is definitely an excellent service and had inspired me for this work, thank you for that!
Glad to hear it's back on track now.
