When a male HUD is connected to a female HUD the male HUD user can now click on the blue sign to ejaculate instantly
When a male HUD has "Poly" installed and active and is connected to a female HUD, the female HUD user can also click the blue sign to make the male HUD cum at her bidding.
Also maintenance works done
you must swap from your older HUD to 3.8- otherwise the updater will keep sending you updates. I strongly recommend that you search your inventory for something like 'allpa' so the filter will list all HUDs you have. If one of them is in a stored outfit, also as link, and you wear it, it will trigger another update. So, if you want to be really 100% sure, remove the old versions.
Firestorm viewer (and maybe others too) offer a fast and easy way to swap links in stored outfits. read more here: https://wiki.firestormviewer.org/fs_linkreplace
Your data are safe. technically the HUD is only a display for data that are stored on a server. When the HUD is updated it is nothing more than a new surface.
Thank you for your understanding.
The updater will send it to you on log in or when you attach the HUD. However, it is SL, sometimes you may just receive the notice and not the item. That is no big deal, here you will see how you can fix that:
Make sure you have not blocked Tantrica Banana. This is by far the most common reason for failed deliveries. Search her name in the SL search and open her profile. You will see at the bottom of the profile buttons for blocking and unblocking.
The updater only accepts requests in intervals of 15 minutes. So, frantically attaching and detaching will not speed up the process. Wait, 15 minutes, then try again.
You can also teleport to the Mama Allpa Region (Link is in your HUD, under "Help" and then "Doctor Appointment") and hit "Redelivery".
To the left of the Casper-Redelivery is an alternative panel for a different way of redelivery. Try that.
Then you have blocked Tantrica Banana. See above.
