First, I had this signature: Kubek15 Talk · Userboxes · Contribs, but I had to paste it (not using ~~~~!), because it was too long to be placed in Signature field in Preferences.
Then, I had this signature for a long time: Kubek15 - Talk, Userboxes, Contributions, but I changed it, because it looked crappy.
Next, I had this signature: Kubek (Talk) • (Sign!) • (What I've done), but, It was too long, as the first one and it hasn't had Userboxes field.
Then, I had this signature for some time: Kubek (Talk) • (Sign!) • (What I've done), but it also hasn't got Userboxes field.
At last, I had this signature: Kubek15 (Sign!) (Contribs) (UBX) And I wanted to have "•" as the spaces between two links, but then it was too long...
