In your Sign-Up.to account you can easily post an update to your Facebook and Twitter account from the Share section. You'll first need to make sure you've integrated your Facebook and/or Twitter accounts with your Sign-Up.to account.
To create a new update, click 'Schedule social post'.
This opens the 'Post to your feeds' box. Here you have the option to post to any or all of your integrated Facebook pages and Twitter accounts simultaneously. Simply click to toggle each one on or off.
There are three types of update that can be selected by clicking the icons.
Simply type your update into the box. You can include URLs here and Sign-Up.to will automatically shorten them to reduce the number of characters they use. Posting to Twitter will put a 140 character limit on your post, regardless of whether your update is also posting to Facebook.
Browse for an image here or drag and drop files from your desktop. You can also type text into the main update box to be posted with your photo. An image can be posted simultaneously to both Twitter and Facebook. Images posted to Facebook will be added to your 'Wall Photos' album. Images posted to Twitter will be added to your Twitpic account.
A link can only be attached to a update if you are posting to Facebook. Enter a URL into the link box and click 'Attach'. Tick the 'No thumbnail' box to remove the image associated with the link. You can also include text to be posted with your link. Links cannot be attached to Twitter updates in this way – use the standard text post function for this. If posting to both Facebook and Twitter simultaneously, an attached link will not be included in the Twitter post.
Once you are ready to publish your post, click 'Share now' to be taken to a preview. Here you can either click 'Share!' to publish your post immediately, or 'Return to post'.
You also have the option to schedule a post to be published in the future. Click 'Share later' to be shown a preview of your post as well as options to set the date and time for publishing. Scheduled posts will appear in Share and can be cancelled if necessary.
