Hi Donte,
Thanks for the fast response, and based in your your answer for me the webinar will be the best solution for my needs 
I have another questions, if possible to answer;
Q#1
based on other forum posts:
Based on this post some users was with problems running one/multiple webinars with more than 300 attendees using web SDK … Was more than one user reporting this in the post … Is this issue resolverd ?
I need to run at same time 10+ different webinars, so if this is not resolved it’s better I create separate Accounts, if is resolved I can have 10+ users in same account with webinar add-on enabled.
This is really important for me take sure because all attendees will be web SDK based.
Q#2
I about webSDK allow join as host or as attendee, but is possible also join as Pannelist ?
Q#3
This is about AndroidSDK, but if someone can answer me here, because is related, in a webinar can a user join as Panelist ?
Thanks for all and keep good work in this great forum.
