Closing a board in trello

Close a board by selecting "Close Board" from the board menu (open the  board's menu and click the "More" button to expand the menu options). You have to be an admin of a board to close it. In Business Class teams, the team admin can also close the board.

Other board members will receive a notification that the board has been closed.

to reactivate: Once a board is closed, it is no longer visible in your Boards list and can only be accessed by clicking the Boards button at the top left of your Trello page and selecting "See closed boards..."

Fixing mouse click

Adjusting Mouse Click Sensitivity

1. Display the Control Panel.
2. Click the Hardware and Sound category.
3. Click the Mouse link, under the Devices and Printers category. Windows displays the Mouse Properties dialog box.
4. Make sure the Pointer Options tab is displayed. (See Figure 1.)

Figure 1. The Pointer Options tab of the Mouse Properties dialog box.

You may need to play around with the settings in the dialog box a bit; the major thing to check is your pointer speed. There have been reports that if the speed is set too slow or too fast for your mouse, it can result in some erratic behavior—like that reported by Donna.

google groups - making emails accessible to managers in addition to owners

It appears that there were restrictions set (perhaps accidentally) so that only the owner of the group can view e-mail addresses.

As a manager of the group, could you try fixing this by:

• After entering "Manage" in the main group page, scroll down to "Permissions".
• Expand the "Permissions" tree, and then select "Access permissions". 
• Within this webpage, should be a section named "View Member Email Addresses"
• Activate the "Select groups of users" button, and select "Managers of the group"
• Activate the "Save" button to save your changes

Clearing out Synaptic lock files

Problem:

E: Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?  




You can delete the lock file with the following command:

sudo rm /var/lib/apt/lists/lock

You may also need to delete the lock file in the cache directory

sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock

After that, try opening Synaptic again.
