I now see you have reached out in Steemit.chat. As I was travelling back from my holiday I had not seen your message. In your message you ask about using the name SteemFest, but only if you have my 'blessing'. Now I am not a god, but certainly did initiate the event SteemFest. So you mention you will only use it when I say it is ok. However you don't wait for a reply from me. That's pretty weird.
This is just using the brand, carefully build up since 2016.
Here is my reply in Steemit.chat:
You could have waited with a post until a reply from me. You could have mailed me. No it is not ok to use the name SteemFest. This is reserved for the event we intend to organise annually. Why? We want to bring together as many people as possible. It is a centralised event around a very decentralised community. The idea is that by having a clear 'wave' in events, people have time to prepare, come and don't feel in doubt whether: should I go to this, or to that one. It has been only 3 months since last SteemFest and the event for this year is already in preperation. Your post received so many upvotes because it uses the name SteemFest. But you have not asked (or waited for) permission to use it and just blatantly post and use the name. I am very disappointed.
Please refrain from using the name SteemFest in any of your event communication, also not tricks like: "The event formerly known as SteemFest 2.5" whatever and delete this post or adjust the post.
For completeness here is the message sent midnight 3.30 AM about 36 hours before this post was made.
