Hey, I saw the new series we have going on. IMO it looks great, no complaints. Since you are starting new and prob gonna carry it over into smash 4, let me through you some tips that helped me grow HOBO.
1. Make accounts at gamefaqs/neogaf/AiB/MLG/VGChartz and other gaming sites like FB/Twitter/google+. ADVERTISE YOUR EVENT AT EACH OF THESE SITES AND CONSTANTLY POST/CHECK ON THEM.
2. Make the thread/event STAND OUT! If you wanna use gifs, use AWESOME ones that make people laugh or cause them to post and say "nice gif." Use colors, stupid sayings(buffalo bich....ect) and just make the thread YOUR OWN.
3. Side events. For HOBOS, I wanted every side event(no BS like project M or brawl+) to supplement the main events. Low tier single/doubles, mid tier single/doubles or crews(low or mid tier). I did this because it gives the mid tier/low tier players a 2nd chance to make money because brawl doesn't allow those characters to do well in normal singles/doubles. It also gives everybody in the city exp in low/mid tier MUs so that when they travel they will not be unprepared.
4. Getting OOS or OOC(ity) is kinda hard. What I did was I choose an OOS/OOC player I wanted to come to a HOBO and privately PMed them and offered a 100% free HOBO(all event fee/venue fee/housing/transportation). Make them feel like they are wanted, respected and are a guest of honor. I recommend you try and get lee for this event. He has not been here in AGES.
5. I make an empty results thread the night before HOBO and put the twitter/livestream link there so that it forces the public to be viewing/refreshing that page over and over in order to see the latest updates. The more views a thread has, the more hype it seems to get.
