Just a weak question, may I ask how the brothers found out about the TGE event in advance?

If I remember correctly, I refreshed the web3 wallet TGE section at 9 AM and didn’t see any announcements. After dinner in the evening, I checked my phone and found that the subscription was already done. I only participated in two out of seventeen TGE events by chance, and perfectly missed the rest. Is there any way to find out in advance?
