Registration example

This section presents a fictitious scenario to illustrate the registration process.

Sally is a professor and ACM member whose group got 3 papers accepted (in the tracks named above) which she co-authored as follows:

  • Paper 7, with John (student ACM member).
  • Paper 11, with Lisa (student non-ACM member) and Mark (student non-ACM member). 
  • Paper 13, with Matt (a professional ACM member) and Jane (a professional non-ACM member). 

Notice that 3 registrations of “Speaker” type are required. Assuming that all will attend and that they pay before the Early deadline, an option that minimizes the registration of their collective fees is:

  • Sally registers for Paper 13 for which she will pay £ 50.
  • John registers for Paper 7 for which he will pay £ 50.
  • Lisa registers Paper 11, for which she will pay £ 50. Mark decides to save some money and becomes an ACM member before registration, thus his registration fees are £ 0.00 (free).
  • Matt registers as an ACM member, thus his fees are £ 0.00 (free). Jane registers as a professional non-ACM member, her fees will be £ 25.00.


Registration for Workshops, Tutorials, and Doctoral Symposium

The registration to SPLC’21 is all-inclusive. Nonetheless, we ask you to please indicate the tutorials and workshops that you plan to attend. This information will help us to configure the conference platform to better suit the needs of the activities.

Registering as Speaker type — Specification of Your Papers 

For this type of registration, you will be asked to indicate the paper that you are registering and their EasyChair ID number and title. For the latter, there will be a free-format textbox. As a paper could have more than one ID associated with it, please use the lowest value.

Registering as an ACM member — Membership Validity Check

Registration in both categories of ACM member (student and professional) requires a valid membership. Cvent, the registration management system of ACM, will check the membership against the forwarding email address stored in the member’s record. Thus for SPLC’21 registration please enter the forwarding address of your ACM membership.

For example, if Sally’s ACM email address is and her forwarding email address is Thus, Sally must use her email address for her registration to SPLC’21.

Tip: To make sure everything is OK with your ACM forwarding address, you can send yourself an email to your account and check that it is forwarded correctly.

ATTENTION!!! Please be aware that the first choice that you will make in the registration process is to select between ACM Member Registration and Non-Member Registration. Hence, please select ACM Member Registration option only when you are not creating a registration of “Speaker” type.

Registering as Student Non-ACM Member — Student Status Proof

If you are not a member of ACM and want to register as a student, you will be required to upload a proof of your student status. Examples of valid proofs are a picture of your student ID card or an official letter from your advisor or university explicitly stating that you are a student. You can use any standard file format such as PDF or JPG, with a maximum file size of 10MB
