Put the signature file sent to you by others in the space, and then click Properties to get the address. After entering I Post Bar, select Personal Settings, which has signature file settings. After registering for more than 3 months, it will appear: add a signature file, click, put the address link, click OK, wait for the approval of Du Niang, and you can use it! Try not to use the address of the picture in the post bar, because if someone deletes the picture, your signature file will be invalid!
