Hi, I'd like to post a texture pack but don't know how to attach the file. Please help?
You can't on this forum. You have to upload it to a storage site such as Dropbox or Mediafire and then post the download link in your thread.
Make sure you read the forum rules before posting. A LOT of new people don't read them and end up getting their posts removed. For starters, you're required to have at least one picture or video in your thread. I recommend Imgur for pictures and Youtube for videos.
Additionally, you absolutely can NOT use any material that you did not creature yourself in your pack. This includes stuff from other packs, pictures from Google image search, and music you got off of Youtube. The only exception is if you have the original author's permission and can post PROOF of that permission in the OP of your thread.
Make sure you don't make these mistakes because I'm tired of having to report people for them. Can't wait to see what you contribute to this forum now that you know how to post stuff!
