Soliciting for YouTube subscribers and/or viewers is not permitted within the community forums as it is considered spam.
Please be sure to review the community guidelines prior to posting. Community Forum Etiquette and Guidelines
You can still post your Youtube channel but only if you post correctly by the guidelines and are not here for us to gain you views or subscribers. Usually you can get away with posting an adequate description and maybe a reason why your video's/channel is helpful to the community and how we may enjoy or benefit in a learning experience from such.
Also, you are only allowed one thread per user, so you must update only one thread if there are new videos you would like the community to see.
Although I am glad to view your channel as it is, since you weren't here to make a fuss and obviously didn't realise, these are the rules the forums have and it's only fair to follow them, since we all do as well.
Hope this helps!
