I would wait a few minutes while I read the new Affiliate's profile to give me an idea where he/she's coming from so I can personalise my welcome letter. Then I would compose my letter with a warm welcome to SFI and to my marketing team, and offer of assistance as a Sponsor, and a request to send me an e-mail if additional information is needed. To initiate a chat on line can be problematic due to time and language differences.
